' a citizen of the United States, residing at ,Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements in Cash Registers, of which I declare the following to be afull, clear, and exact description.

' registers and like machines.

This inventionrelates to ink ribbon feed ing mechanism adapted for usewith cash The subject matter of this application constitutes a divisionof co-pending applik .c ation of the same inventor,. numbered 451.508,and filed March 11, 1921. The rincipal object of this invention is toprovide means under control of the rib-' bon itself whereby the ribbonwill be given an extra long feed at certain points in its movement.

. -.With these and incidental objects in view,

the invention consists of certain novel features of construction andcombinations of parts, the essential elements of which are set forth inappended claims and' a preferred form of embodiment of which ishereinafter described with reference to the drawings whichaccompany andform'part of this specification.

General desm'z'ptz'on;

The printing mechanism disclosed com:v

prises two sets of printing wheels or elements 19 and 20 with whichsuitable-impression hammers 21 and'22cooperate to produce impressions ona detail strip 23 and a slip 24 through afribbon 25. The ribbon is sewedso as to make it a continuous ribbon and cooperates with both sets ofprinting elements. It was found that when the seam in the ribbon cameopposite either type line ent invention contemplates so constructing thefeeding mechanism that when the seam in the ribbon approaches eitherprinting The presare supported by studs 29 projecting from a frame 30.This method ofmounting is convenient in that by removing the abovementioned plate the entire ribbon and ink roll may be removed fromthemachine.

A tension is maintained on the ribbon 25 by a roller31 on a rod 32(Fig. 1) supported by parallel arms 33 (only one of which is shown),loose on a stud 34 mounted in the frame 30 and supported at its outerend by the above mentioned plate The roller is held against the ribbonby gravity.

Clutched tothe roller 27 by any suitable means (Figs. 3 and 4) is aratchet 35. Loose on the stud 36 which supports the ink roller is anarm- 37 carrying a springpresseddriving pawl '38 engaging the ratchastud on the frame and a flat-sided stud 45 on the link 39 holds thepinin engage- 'ment with a toe 46 of an arm 47 loose on a stud 34 therebylimiting the downward movement of the link 39.

The lever 42 is rocked firstcounter-clock- I wise and then clockwise(Fig. 1) by means of the following mechanism. Fast on the shaft 43 is anarm 49 (Figs. 1 and 2) to a which is pivoted one end of a pitman 50.This pitman at its otherend is slotted to surround a hub 59 of a cam 54fast on a shaft 51, which receives one complete counter-clockwiserevolution upon each operation of the machine. The pitman 50 carries ananti-friction.roller 52 cooperating with a cam groove 53 in the cam 54;The shape of the cam} groove 53 is such that the pitman rocking arm 49,shaft 43 and lever 42 counis moved first to the left and then towardsthe right back to home position, thereby its highest position, and whenthe lever ter-clockwise and then clockwise. Near the end of thecounter-clockwise movement of said lever the pm 41 engages the end otthe slot 40 and moves the link 39 upward, there spring 44 lowers thelink 39 and returns the arm 37 and pawl 38 to the position shown in Fig.4. A spring-pressed retaining pawl 56 prevents clockwise or retrogrademovement of the ratchet 35.

The ribbon has a transversely extending seam 57 (Fig. 1) and, as animpression through said seam would not be clear. a mechanism is providedfor feeding the ribbon a greater distance as the seam approaches theprinting lines so that it never stops at these lines.

Secured to the ribbon are two metal buttons 60 cooperating with a flange($1 of an arm 62 rigid with the ar1n47. IVhen one of the buttons 60engages the flange 61 during the movement of the ribbon, it rocks thearms 62 and 47 clockwise and disengages the toe 4.6 from the stud 45thereby allowing the spring 44 to move the link 39 downward, whereby theend of the slot 40 is moved close to the pin 41. Downward movement ofthe link 39 also rocks the arm 37 a greater distance than previouslydescribed.

IVith the parts in the positions just mentioned, the pin 41 engages theupper end of the slot 40 during the first part of the counter-clockwisemovement of the lever 42 and .moves the link 39 upward, whereupon thearm 37 is rocked counter-clockwise. As this movement of the link 39 andarm 37 is much greater than that previously described, it is clear thatthe ribbon is fed agreater distance than when the button 60 does notrock the arms 62 and 47 to disengage the toe 46 from the pin 45. Duringthis movement of the ribbon the button (30 which caused the long feed ismoved past the flange 61 on arm 62 so that the arm 47 by its own weightis rocked counter-clockwise after the pin has been moved to 42 is rockedclockwise to its normal position the spring 44 pulls the link 39downward until the stud 45 again ei'igages the too 46 ion the arm 47.The lower edge of the toe .46 is'sh aped so that the upper surface ofthe stud 45 can cam the arm 47 clockwise to permit the link 39 tocomplete its upward movement in case the 'button leaves the flange 61during the first part of the upward movement of the link 39. These twobuttons are so positioned on the ribbon that the seam 57 is always tedpast the printing lines and therefore no impression is ever taken onsaid seam.

IVhile the form of mechanism herein shown and described is admirablyadapted to fulfill the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form ot" thecombination of an inking ribbon, a seam therein, type carriers, meansfor feeding said ribbon over said type carriers, and means under controlof said ribbon and operable as the seam approaches said carriers forcontrolling said feeding means to feed said seam from one side of saidtype carriers to the other.
